But the saber-tooth was already at his heels, before he had time to swing quite out of reach. The gigantic brute gathered itself for a spring which would have enabled it to pluck Bawr from his refuge like a ripe fig. But that spring was never delivered. With a roar of rage the monster turned instead, and bit furiously at the shaft of an arrow sticking in its flank. Grom's second shaft had flown true; and Bawr, greatly marveling, drew up his legs to a place of safety. With the fire of that deep wound in its entrails the saber-tooth forgot all about its quarry in the tree. It had caught sight of Grom when he uttered his yell of warning, and it knew instantly whence the strange attack had come. It bit off the protruding shaft; and then, fixing its dreadful eyes on Grom, it ceased its snarling and came charging for the ledge with a rush which seemed likely to carry it clear up the twenty-foot perpendicular of smooth rock. Grom, enamored of the new weapon, forgot the spear which was likely to be far more efficient at these close quarters. Leaning far out over the parapet, he drew his arrow to the head and let drive just as the monster reared itself, open-jawed, at the wall. The pointed hickory went down into the gaping gullet, and stood out some inches at the side of the neck. With a horrible coughing screech the monster recoiled, put its head between its paws, and tried to claw the anguish from its throat. But after a moment, seeming to realize that this was impossible, it backed away, gathered itself together, and sprang for the ledge. It received another of Grom's shafts deep in the chest, without seeming to notice the wound; and its impetus was so tremendous that it succeeded in getting its fore-paws fixed upon the ledge. Clinging there, its enormous pale-green eyes staring straight into Grom's, it struggled to draw itself up all the way--an effort in which it would doubtless have succeeded at once but for that first arrow in its entrails. The iron claws of its hinder feet rasped noisily on the rock-face. Grom dropped his bow beside him and reached for the spear. His hand grasped the club instead; but there was no time to change. Swinging the stone-head weapon in air, he brought it down, with a grunt of huge effort, full upon one of those giant paws which clutched the edge of the parapet. Crushed and numbed, the grip of that paw fell away; but at the same moment one of the hinder paws got over the edge, and clung. And there the monster hung, its body bent in a contorted bow.
